Actors George Takei and Hal Sparks have criticized Supreme Court Justice Antonin Scalia's comparison of gay sex to murder.

Speaking at Princeton University to promote his book, Reading Law: The Interpretation of Legal Texts, Scalia was asked by a gay student about his previous controversial writings on gay rights.

His form of argument, Scalia answered, was “reduction to the absurd.”

“If we cannot have moral feelings against homosexuality, can we have it against murder? Can we have it against other things?” Scalia asked. He added that he was not equating sodomy with murder but drawing parallels between laws which ban both, the AP reported.

In an appearance on MSBNC, Takei called the statement “repugnant,” and stated that Scalia should step down from ruling on two upcoming cases related to gay marriage.

“Any justice who has so little thought before he speaks should not be participating in ruling on the cases involving DOMA or Proposition 8,” he said. “He is clearly biased in this situation. So how can he look at the issue and make a judgment fairly?”

“That man is a nut job,” Hal Sparks said on The Stephanie Miller Show.

If you think the argument is effective “there is something tweaked about you,” he added. “That's a sociopathic reflex, because you think somebody's behavior is on par with the elimination of someone's life.” (The video is embedded on this page. Visit our video library for more videos.)
